WAGON-LOADING DEVICE.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed June 20, 1908. Serial No. 439,571.

To all whom t may concern:

Be it known that I, RAsMUs PEDERsoN, a citizen of the United States ofAmerica, and a resident of Parkersburg, Butler county, Iowa, haveinvented certain new and useful Improvements in Wagon-Loading Devices,of which the following is a specification.

My invention relates to improvements in wagon loading devices, and theobjects of my improvements are these First, to provide an improved formof bail for the loading fork; second to furnish an improved method ofsuspending said fork to keep it in equilibrium third, to construct anovel and ellicient form of clutch-mechanism for the draftcable of thesaid fork; fourth, to supply a trussed substructure adapted todetachably support the su erstructure of the Vknockdown framewor i ofthe loading device when it is desired to support such superstructureapart from a wagon to be loaded thereunder, and fth, to so modify therear part of-said superstructure as to adapt it for use either with saidsubstructure or with the wagon on which it may otherwise be removablysupported.

These improvements are designed to be improvements in the constructionand use of the form of wagon loading device, which is illustrated,described and claimed in my former application for patent, led in theAUnited States Patent Office under Serial Number 405,875, on December10, 1907.

These objects I have accomplished by the means which are hereinafterfully described and claimed, and which are illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of my improved wagonloading device, assupported on my new substructure over a wagon. Fig. 2 is an enlargeddetail side elevation of the mounting of my improved draft-cable clutch.Fig. 3 is a-n upper plan view of the middle and side framing-tubes andtheir connections of the superstructure. Fig. 4 is a transverse sectionof the loader and its substructure looking toward the rear and taken onthe line a-b in Fig. 1. Fig. 5 is an enlarged longitudinal verticalsection of thel clutch mounting shown in Fig. 2. Fig. 6 is a sideelevation of my improved form of fork or scoop. Fig. 7 is a frontelevation of my improved bail for the fork or scoop and its provedmethod of suspension for securing its equilibrium.

Similar numbers refer to similar parts throughout the several views.

The knockdown superstructure of my wagon loading device consists of thefollowing separable elements. The forward crosstube 50 is connected bycouplings 64 to the side tubes 9 and 65. The rear cross-tube 66 isconnected to said side tubes by the couplings 48. The forward uprightsor risers 78 are connected to said cross-tube 50 by couplings 77, whilethe rear risers 19 and 74 are pivotally connected to the cross-tube 66by couplings 51 and 20 respectively. A medial longitudinal tube 8 issupported upon the crosstubes 50 and 66,- and secured thereto bytruss-rods 73 and bolts 12, also by corner supports 49 and bolts 12 and75. Fixed braces` 5 connect the front risers 78 to the side-tubes 9 and65. 18 designates a brace on each side whose upper end is fixed to theside-tube above it, and whose lower end is adapted to be detachablyconnected to the lower end ofthe adjacent rear riser by a bolt 79. Alongitudinal truss-rod 4 connects the ends ofthe medial tube 8. A Y-rail13 is suspended from and under the medial tube 8 on hangers 3, 6, 10, 11and 12, the rear end of said rail extending rearwardly a desireddistance -beyond the risers 19 and 74. The detachable substructure forsaid'superstructure is shown in Figs. 1 and 4, and consists of cornerosts 29 and 32 at front and rear respective y, said postsbeingfsuperposed on the ends4 of the parallel longitudinal beams 53, andsecured thereto by struts 76, and by truss-rods 37 having holding-bolts39. Said posts are also connected at the ends by crossbars 52 and 72,and by rods 34. The bolts 36 secure the ends of said truss-rod 37 to thecorner-posts 29 and 32. 38 is another trussrod on the under side of eachlongitudinal beam 53, and secured to it by the bolts 39. The wholeVforms a light, rigidly braced structure, which may be anchored to theground,

j if desired, by means ofthe pegs 47 and connecting links 46.

The lower, ends of the risers 78 and 19 have downwardly projecting pins27 which may be received, as desired, either in the orificed brackets 41and 42 on the wagon 28, or in the orificed brackets 25 on the upper endsof the posts 29 and 32. When supported on the substructure postsmentioned at ,29 and 32 the risers are vertical as indicated by the fulllines in Figs. 1 and 4, but when the superstructure is to be placedupona wagon 28, the bolt 79 is withdrawn from the lowermost seat in each ofthe risers 19 and braces 18 on each side, and inserted in the uppermostbolthole of the braces 18 and the uppermost bolt-hole 35 of said risers.This brings the risers forward obliquely, which places them in a betterposition to sustain the strain when the overhanging superstructure isapplied to such awagon.

7 is a wheeled carriage adapted to ride suspended upon the Y-rail 13,and has a pulley 14 pivoted in its hanging portion over which passes thedraft-cable 30. The cable 30 may be moved forward by a horse hitched tothe swingle-tree 3 1, the cable being passed over the fixed pulleys 44and 2, the latter connected to a hanger 1 of the superstructure. Therear end of the cable 30 is attached to the rear portion of the carriage7, and a rolling pulley 54 is supported on the slack of the cable 30between the fixed pulley 14 and the point of connection of said cablewith the rear end of the carriage 7.

A fork or scoop 71 is suspended from the block of the pulley 54 by arail 57 having rearwardly curved members 58 and 59, the latter beingpivoted at 60 to the side tines 16 of the fork 71. The pulley 54 ismedially connected to said bail by a link 56, and also bychain-connections extending obliquely at 55 to the bail 57 at pointsnear its corners. These oblique connections serve to keep the fork orscoop in equilibrium in case a little more weight of load is located onone side thereof than on the other. A chain-connection 82 serves toconnect the middle of the bail 57 to the rear upper part of the fork 71and limit its amount of forward play. The bail-members 58 and 59 arerearwardly bent as shown in Fig. 6, and this form is useful when loadingmanure having straw as a component. The members so bent afford aclearance on the sides of the scoop for any projecting` straw, andprevents any clogging of such a load.

The fork 71 consists of side members 16 with intermediate tines or aplate scoop as desired, connected together transversely in any suitablemanner, the upwardly curved side pieces being braced by the bars 61 and62. 63 is a rearwardly-projecting handle on each side of the fork orscoop 71 used to guide it when taking in a load.

17 is the dumping-rope, and is connected to the rear part of the fork orscoop a little in advance of its center of gravity, Said rope 17 isconducted back over a dentated clutchmember 69, the latter being pivotedat 67 in the lower part of the casting 23. This casting has acylindrical plug 43 adapted to be seated in the rear end of the tube 8and secured thereto by a bolt 81. The rear por` tion of the casting ishood-shaped to contain the movable clutch-member 69 and has a rearwardprojection on one side of which a small pulley 68. The inner curvedsurface of the casting 28 opposite the member 69 is provided withcounterpart deutations, whereby, when the member 69 is moved upward therope 17 is caught and held securely between the opposing dentations ofsaid parts. The member 69 is moved upward by means of a pull-rope 40connected to the rear part of the member 69 and then passed over thepulley 68. Then the pull-rope is at rest the member 69 drops releasingthc dumping-rope 17. /Vhen the fork or scoop has been elevated with itsload by the means mentioned and then drawn forward to the proper placefor dumping, the pull-rope 40 being pulled down causes the clutch-member69 to catch and hold the rope 17 against the dentated .face of thecasting 23, and the draft on the cable 30, draws upon the rear part ofthe fork enough to tilt it forward as shown in Fig. 1, dumping itscontents into the wagon 28 thereunder in a desired location.

In practice, the tube 8 and Y-rail 13 are sufficiently inclined from thefront rearwardly as to permit the carriage 7 with its suspended fork orscoop 71 to move rearwardly by gravity when the fork is unloaded. thepull-rope 40 released from the clutch` and the draft removed from thecable 30. The fork or scoop then moves backward, as far as the end ofthe rearwardly-projecting end of said Y-rail, where the fork or scoopmay be permitted to descend and be drawn back along the ground forreloading.

claim as new, and desire to secure by Letters Patent, 1s:
